Acura and Cadillac shine, BMW and Porsche falter at the Rolex 24

The new prototypes put on a good show for a packed crowd at the 24-hour race.

DAYTONA BEACH, FLA.—With just one race on the books, it's probably too soon to declare this the dawn of a new golden era in racing, but that thought was on many minds at last weekend's spectator-packed Rolex 24 at Daytona. The grueling 24-hour race is the season-opening event for the WeatherTech Sportscar Championship, and 2023 saw the introduction of a new class of hybrid prototype race cars called GTP (for Grand Touring Prototype).

The crowds were heavier than ever, buoyed by the debut of the new machines, which put on a good show. And the complicated new energy-based pit stop formula didn't appear to present anyone any trouble.

The same can't be said for the race itself. Twenty-four-hour racing is hard—I speak from some experience—and making it to the end should be, and is, a challenge. A 24-hour race as the first race of the year for all-new cars is even more difficult, despite the thousands of miles each car covered in testing over the past few months. As such, some feared we might be in for a repeat of 2003; that year saw a new prototype class introduced, the best of which finished 24 laps behind the winning car, a racing version of a Porsche 911.

Rocket Report: Tearing down Ariane’s SUSIE concept; is ChatGPT a rocket scientist?

“If you have someone who is worried, don’t slough it off. Deal with it.”

Starlink 5-3, SpaceX's 200th orbital launch, takes to the skies with a fitting 53 Starlink satellites early Thursday morning. (Thanks, cloud).

Welcome to Edition 5.24 of the Rocket Report! I joined Ars more than seven years ago to write about space. It has been an amazing ride, and now I'm thrilled to say we're expanding our coverage. Come work with me as a space reporter! Pay is competitive, and you can work remotely. But you must be passionate about space and writing. At least some experience in space journalism is preferred. Here is the place to apply. Anyway, in a few months, I hope to have someone to help with the Rocket Report, so there will no longer be interruptions!

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

A deeper dive into the German launch industry. A German market research firm, Capitol Momentum, has published an extensive report on the financial and technical health of Germany's three most prominent small launch companies—HyImpulse Technologies, Isar Aerospace, and Rocket Factory Augsburg. The report (which requires an email address to download) provides a trove of data about the companies, which are all attempting to bring orbital rockets online within the next 12 to 24 months.

Hybride Arbeit: Das neue Normal braucht bessere Ideen!

Nach dem Pandemie-erzwungenen Homeoffice schalten manche Firmen auf Dauerremote um, andere auf Büropflicht, wieder andere auf hybrid. Nichts davon funktioniert gut – weil es an Konzepten fehlt. Ein Appell. Ein Erfahrungsbericht von Marvin Engel (…
